Application filed January 15,1908. Serial No. 139,209. (No model.)

To all whom, it may concern:

Be it known that I, BENJAMIN FRANKLIN SMITH, a citizen of the United States, residing at Seattle, in the county of King and State of Washington, have invented certain new and useful Improvements in Machines for Painting Shingles; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to improvements in machines for painting with or applying to shingles paint, creosote, or other preserving compositions; and it consists in a machine provided with liquid-applying rolls for engaging the shingles upon both sides and means for delivering liquid paint, creosote, or other preserving compounds to the said rolls.

It also consists in a machine provided with a paint or other liquid reservoir, means for agitating the paint therein, rolls for applying the same to shingles, and means for delivering the liquid continuously to said rolls as the shingles pass between them.

It further consists in certain other novel constructions, combinations, and arrangements of parts, as will be hereinafter fully described and claimed.

In the accompanying drawings, Figure 1 isa portion of the machine, showing the applying-rolls and the means for delivering the shingles thereto, together with a paint-delivering mechanism. Fig. 3 isa transverse sectional view through the central portion of the machine on a line with the wiping-rolls, a portion of the rolls and the operating mechanism being shown in elevation. Fig. iis a detail fragmentary view of one of the rolls, illustrating the manner of wrapping the circumference with material suitable for applying paint or other liquids.

In using wood shingles for the roofs of houses it is customary to dip or paint the same with some preserving compound, as creosote, paint, or other water-excluding material, so as to preserve the shingles and lengthen their life. This operation has very generally been done by hand and consumes considerable time, it requiring the painting of a great many shingles for the roof of a single house.

The object of the present invention is the construction of a machine which can be made to apply such preserving compound to shingles in a quick and thorough manner and also at a saving of the liquid applied.

I have illustrated in the drawings a preferred form of mechanism for accomplishing the desired result and shall describe the invention, having reference to said drawings.

In the drawings a frame 1 is shown formed with vertical posts 1, which carry near their upper ends an upper platform 1". A tank 2 of any desired shapeis mounted upon the upper platform, the said tank being quite deep. Between the posts 1 of the frame is also mounted an inclined platform below the upper platform composed of certain inclined floors and chutes, as will be hereinafter fully described. This tank may be open at the top and is provided with a vertical shaft 3, carrying paddles 4 of any desired construction, which paddles extend to a point near the bottom of the tank, so that by rotating the shaft the mixture within the tank can be thoroughly agitated and kept in a well-mixed condition. The shaft 3 carries a beveled gearl5, which is made to mesh with a gear 6, carried by a horizontal shaft, extending to one side of the tank and provided with a suitable sprocketwheel, as 7. This sprocket-Wheel 7 may be connected by a sprocket chain 8 witha sprocket-wheel 9, mounted upon the frame 1 below the tank, where it is in position to receive motion from othermechanism, as Will be hereinafter described. The paddles in the tank 2 may thus be kept in motion when the machine is operating upon shingles.

Below the tank 2 and upon standards of the frame 1 are mounted applying and wiping rolls. "While I may use any desired number of rolls for this purpose, I usually employ two applying-rolls, as 10 and 11, and as many wiping-rolls, as 12 and 13. These rolls are used in groups,the applying-rolls having their peripheries close together and the wipingrolls having their peripheries close together, as shown in Fig. 2. The applying-rolls 10 and 11 are preferably arranged at a point in the frame 1 which is a little higher than the position of the wiping-rolls 12 and 13. The shafts which carry these rolls extend outwardly at each end thereof and engage adjustable bearings upon the side standards of the frame 1, as shown in Fig. 1. The bearings, as shown at 14, may be provided with screws engaging elongated slots in the cap-plates ofsaid bearings, so that the bearings may be adjusted to bring the rolls closer together or to separate them, as found necessary for the best operation of the mechanism. The ends of the shafts are provided with gear-wheels, so that the upper rolls turn in correspondence with the lower rolls in each instance. Thus the applying-rolls 10 and 11 are provided at the ends of their shafts on one side of the machine with intermeshing gears 15 and 16, while the shafts of the wiping-rolls l2 and 13 carry upon the other side of the frame intermeshing gears 17 and 18. The shaft 19 of the lower wiping-roll 13 is preferably provided at one end with a driving-pulley 20, which receives power from an engine or any other suitable source of motion, while the other end of the shaft 19 carries a fly-wheel 21. The group of wiping-rolls 12 and 13 thus receive their movement from the shaft 19. The movement of this shaft 19 is also communicated to the lower shaft 22 of the lower applying-roll 11 by means of a sprocket-chain 23, which engages sprocket-wheels upon the shafts 19 and 22, as illustrated in Fig. 1, and at the rightof Fig. 3. The shaft of the upper wiping-roll 12 carries at one end the sprocket-wheel 9, which engages the sprocket-chain 8, and thus drives the paint-mixing paddles, as heretofore intimated. Of course it will be evident that the sprocket-chain 8 might be operated by a sprocket-wheel .upon the shaft of any of the other rolls without departing from the spirit of the invention, and it will also be evident that intermeshing mechanism could be applied to the rolls in other arrangements for causing their simultaneous actuation, all within the spirit of the present invention.

The paint or other preserving fluid is delivered to the upper applying-roll 1O preferably by means of ahorizontal pipe 25, having perforations in its under side, so that the paint is sprinkled along the whole length of the roll 10 upon its periphery as it rotates. The pipe 25 is connected with the bottom of the tank 2 by suitable piping, as 26, controlled by a stop-cock 27. The lower applying-roll 11 is also kept supplied with the preserving mixture by being partially inclosed with a housing or tank 28, the said tank extending around the greater portion of said roll, as illustrated in Fig. 2. Paint may be supplied to this tank by piping 2 from the tank 2or in any other suitable manner, the said paint being preferably kept at such a height in the trough 28 as to immerse about half of the roll 11. This trough being arranged below and around the applying-roll 11 not only supplies the said roll with sulficient quantity of paint, butca'tches any exface of the lower wiping-roll 13.

cess of the liquid which may not be taken up by the shingles and also catches the drippings from the upper applying-roll 10. The shingles are delivered between the applying-rolls 10 and 11 by an inclined floor 29, forming a part of the lower platform. The shingles after passing between the rolls l0 and 11 and receiving a coat of paint are then held between the rolls 12 and 13 by a short inclined floor 30, also a part of the lower platform, which rests at its lower end against the sur- By thus resting upon the roll 13 the floor 30 is in positionto scrape the paint or liquid from the surface of said roll which the roll may have wiped from the shingles. Any scrapings of liquid from the shingles are caught bya semicylindrical trough, as 31, which surrounds a portion of the lower wiping-roll 13. The accumulation of liquids in the tanks 28 and 31 can be regulated at any time by means of drip-cocks 32 and 33, arranged at the bottom of the said troughs. The wiping-rolls l2 and 13 are simply intended to remove any excess of paint or preserving liquid which may remain upon the surface of the shingles after passingthrough the applying-rolls. The shingles after passing through the wiping-rolls 12 and 13 pass down an inclined floor 34, forming the lower end of the lower platform, to a conveyer 35 at the lower end thereof. The said floor 34 may be perforated, as shown in Fig. 2, and a drip-catching tank 36 is arranged below the perforated portion of said floor to catch any drippings which may pass through the same. Thus any liquid which may have escaped the wiping-rolls and the trough 3t will be caught by the tank 36 beneath the perforated door 34. The shingles pass from the fioor 34 upon the endless conveyor 35, which is adapted to deliver the shingles at any suitable or desired point. This endless conveyerpreferablyconsists of side sprocketchains 3'7, which pass around sprocket-wheels ICC IIO

at the upper and lower ends of a frame 38. a

The conveyer-frame is pivoted to the frame 1 at its inner end by a shaft 39, which carries the same. This shaft is mounted in journals secured to the frame 1 and projects beyond said journals at one end, so as to receive a sprocket-wheel 40, which may be connected by a sprocket-chain 41 with a sprocketwheel 42 upon the power-shaft 19, and thus receive motion from said power-shaft. In this way the conveyer-belt will be kept in motion continually when the machine is in operation. The belt of the conveyer is preferably formed of Wire mesh or other suitable material stretched between the chains 37, and a number of transverse cleats, as 43, are applied upon the said belt for positively engaging the shingles and insuring their being lift ed by the conveyer to the upper end thereof. The upper end of the conveyer can be supported at any desired height by a standard 44 or by any other means which may be suitable for holding theconveyer at different heights. The shingles may be mounted upon side extensions 45 of the upper platform, arranged upon each side of the frame 1 opposite the upper end of the chute 29, so that they can. be readily delivered upon said chute 29. The chute 29 may, if desired, be perforated, as shown in the drawings, though this is not essential.

The formation of the applying and wiping rolls is also important in this mechanism. Each one of said rolls is preferably formed with a core or body portion secured to its shaft, which may be made of wood, if desired, and upon the periphery of each of these rolls is applied one or more coverings of yielding material. I find that the best result is secured by winding the surface of the core first with a cotton cord or rope of suitable diametersay five-eighths of an inch-the rope being wound closely from one end of the roll to the other, as shown in the drawings in Figs. 3 and 4. I then preferably apply a second winding of soft cotton cord made of numerous slackly-twisted strands, the said cord being about three-sixteenths of an inch in diameter. This outer wrapping forms the outer coating of each of the rolls and engages the shingles which pass between the rolls. The inner winding of cotton rope makes a yielding background for the outer covering, and as the shingles pass between the rolls they become embedded in these coatings of the rolls, the outer covering being squeezed around the edges of the shingles as well as engaging the top and bottom surfaces, so that the liquid preservative is thoroughly applied to the sides and edges of the said shingles.

In operation the shingles are fed continually down the chute 29 to the applying-rolls, which supply liquid to the shingles to coat their entire surfaces. The shingles then pass over the floor 30 to the'wiping-rolls, where any drippings or excess of liquid is removed therefrom, after which the shingles slide down the floor to the conveyer-belt and are delivered by the same at any suitable point.

It will be evident from the above description that my improved machine is capable of thoroughly coating shingles with a preservative material-as paint, creosote, or the likeand that the object can be attained not only in a rapid manner, but in a very thorough manner as well.

Of course while this machine is primarily adapted for painting shingles, other small pieces of wood or material which can be passed through the rolls can also be painted in the same manner.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. A painting-machine comprising a frame, applying-rolls mounted therein and wipingrolls journaled thereon and painting-surfaces formed on all of said rolls made up of an inner layer of large cordage and an outer layer of smaller cords or threads.

2.
